I took a bunch of files from fps banana and other sources and created this custom sound pack for my game. If anyone wants then you can go and download it. To replace your sound pack directions are as followed. Copy the sound folder and replace it in your files. Ensure you make a copy of your original in case you don't like it. The file location is c:/programfiles/steam/steamapps/your steam log on name/dayofdefeatsource/dod/sound. Let me know what you think. If you're interested in the visual pack I have let me know or you can go to wiledod.com and get your own.
